In his gleeful romp “Billy Witch,”Gregory S. Moss (“punkplay”) takes familiar ingredients of high school horror — summer camp, a lake, a forest, ghost stories — and hurls them into a whirlwind of comic sexual awakening.

The campers include the 14-year-old Oliver (Seamus Mulcahy), a shy outsider seeking to change his life. Change certainly arrives, thanks to puberty, not to mention Oliver’s fair-weather friend Arden (a petulant and amusing Eric Bryant), a boy of drastically arbitrary moods and sexual preferences; the mysterious Kid (Andy Phelan), who strikes a bargain with Oliver; Sandy (Liz Wisan), a garrulous gossip and flirt; and Miranda (Aimee Howard), a shy girl with eyes (and tentacles) for Oliver. We also learn about Billy Witch, a camper who in 1982 vanished in suspicious circumstances and has haunted the premises ever since.

As directed by Erik Pearson, the show pursues strange tangents — Lockwood’s comically terrifying lecture about women, the counselors’ unsettling arts-and-crafts presentation on the preparation and meaning of God’s-eyes — but doesn’t lag. (Nor does the buoyant cast.) And you may never again see the first tentative kiss of adolescence exchanged between a boy and a bespectacled she-squid.
